Don't have my 335 anymore and had this left over.
Procede 2.5 v5 with harness and serial to USB adapter for the N54. The adapter worked on several laptops including win vista, win7, and win8.
The Procede is in perfect condition and is NOT VIN locked so no sending it in and paying extra, the harness has zero bent pins and is also in perfect condition.
Asking $300 shipped and insured
